Before using this feature, verify the following parameters are correct:

•Empty (P006)

•Temperature (P664)

•Offset Reading (P062)

Offset Calibration

Begin with a steady level.

1.Press TRANSDUCER to display the calculated reading.

2.Repeat Step One at least five times to verify repeatability.

3.Measure the actual reading (use tape measure).

4.Enter the actual value.

The deviation between the entered Empty (P006) value and the calibrated Empty value is stored in Offset Correction (P652).

P651 Sound Velocity Calibration

Changes the speed of sound constant.

Condition for use of this feature

•The acoustic beam atmosphere is other than air

•The acoustic beam atmosphere temperature is unknown

•The Reading accuracy is acceptable at higher material levels only

For best results, calibrate with the level at a known value near empty.

Using Sound Velocity Calibration

Ensure a steady level at some low value (P653 and P654 adjusted accordingly)

1.Allow sufficient time for the vapor concentration to stabilize.

2.Press TRANSDUCER to display the calculated reading.

3.Repeat Step Two at least five times to verify repeatability.

4.Measure the actual reading (e.g. with a tape measure).

5.Enter the actual value.

Repeat this procedure if the atmosphere type, concentration, or temperature conditions are different from when the last sound velocity calibration was performed.

Note: In gasses other than air, the temperature variation may not correspond with the speed of sound variation. Turn off temperature sensor and use a fixed temperature.

LU01 specifications

The Siemens LU01 is a state-of-the-art train control and signaling system designed to enhance the safety and efficiency of rail networks. This sophisticated system leverages advanced technologies and innovative features to ensure seamless train operations, lower maintenance costs, and improved overall performance.

One of the main features of the Siemens LU01 is its implementation of the European Train Control System (ETCS). ETCS is a vital component in modernizing rail infrastructure across Europe, aiming to standardize various train control systems for enhanced interoperability among different national networks. The LU01 facilitates the integration of ETCS Level 1 and Level 2, allowing for both trackside equipment and onboard systems to work in harmony to manage train movements effectively.

Additionally, the LU01 employs a decentralized architecture that enhances system reliability and minimizes downtime. This design means that it can operate even in the case of individual component failures, ensuring that train operations remain uninterrupted. Furthermore, the LU01 utilizes advanced diagnostic tools and predictive maintenance technologies to monitor system performance continuously. This proactive approach allows for early identification of potential issues and timely maintenance, which contributes to reducing operational costs.

Another critical characteristic of the Siemens LU01 is its capability for real-time data transmission. The system integrates wireless communication technologies, enabling constant connectivity between trains and control centers. This feature allows for real-time updates on train positions, speeds, and other critical operational data, thereby enhancing situational awareness for train operators and maintaining optimal schedules.

Moreover, the LU01 is designed to be compatible with existing rail infrastructure, ensuring a smooth transition for railway operators looking to upgrade their signaling systems without extensive overhauls. This adaptability makes it an appealing choice for both new projects and retrofitting existing rail networks.

In summary, the Siemens LU01 stands out for its cutting-edge features, including support for ETCS, decentralized architecture, real-time data communication, and compatibility with legacy systems. With these technologies and characteristics, the LU01 significantly contributes to the safety, efficiency, and sustainability of modern rail transport systems, making it a pivotal solution in the evolution of railway operations.
